JOHN B. HUNT, 0F MANSFIELD, OHIO.

Specification of Letters Patent.

Patented July 6, 1915.

Application filed June 17, 1914. Serial No. 845,535.

To all whom it may concern Be it known that 1, JOHN B. HUNT, a citizenof the United States of America, residing at Mansfield, in the county ofRichland and State of Ohio, have invented certain new and usefulImprovements in Apparatus for Setting Fractured or Broken Limbs, ofwhich the following is a specification.

This invention relates to certain new and useful improvements inapparatus for setting fractured or broken limbs, and the primary objectof the invention is to provide an apparatus of the type mentioned inwhich the patient is permitted to freely move the fractured limb up ordown, longitudinally back and forth, or laterally rotate same in ahorizontal plane, as he may desire, within certain restricted bounds,without imposing strain or friction on the injured limb.

Further, the invention aims to provide an apparatus which dispenses withthe weights customarily employed, and employs in lieu thereof, meanswhich draws the fractured limb into place under a determinable pressure.

Still further, the invention aims to provide an apparatus in which thelimb receiving box can be easily and quickly collapsed to permitthe limbto be placed within the apparatus conveniently and with comfort to thepatient.

The invention also aims to provide a structure which can be placed atany point on the supporting surface of the bed, as distinguished fromdevices which employ weights that require room in which to operate.

()ther and further objects will be later set forth, and of themselvesmanifested in the course of the following description.

In the drawings: Figure 1 is a top plan view of the invention; Fig. 2 isa side elevation, partly broken away; Fig. 3 is an end elevation of thebox in which the limb is placed; Fi 4 is an end elevation of thecomplete apparatus; Fig. 5 is an enlarged sectional view on the line 5-5of Fig. 4; Fig. 6 is a top plan view of the base, the box being omitted;Fig. 7 is a side elevation of Fig. 6; Fig. 8 is a section on the line8-8 of Fig. 6; and Fig. 9 is a section on the line 9-9 of Fig. 6.

In proceeding in accordance with the present invention, a base board orplate 1, is employed, preferably reinforced at its ends by cleats 2 and3 which act as a means to prevent longitudinal movement of the board onthe bed. A plate 4 is rigidly affixed to the base 1, and is providedwith an upwardly extending stud 5, which latter projects above the topface of the base 1. An L-fitting 6 revolubly receives the stud 5 androtates in a horizontal plane and is provided with a sleeve 7. AT-fitting 8, has a stub shaft 9 which rotates within the sleeve 7 therotatable movement of the stub shaft 9 being limited by the provision ofa slot 10 formed in the sleeve 7, and a screw 11 which is connected tothe shaft 9 and extends through the slot 10, thereby preventing theseparation of the shaft 9 from the sleeve 7.

The limb receiving box has a bottom 14 which is connected to a plate 13,the latter having a depending stud shaft 12 which is rotatably receivedwithin the vertical part of the fitting 8 so as to enable the box tooscillate horizontally about the stud shaft 12. The sides 15 and 16 ofthe box are hinged thereto at 17, and 18, respectively to .allow them tobe moved outwardly to the dotted line position shown in F 3 so as toconveniently enable the leg to be placed within the box.

The box has an end 19 provided with a vertical extension 20, to whichlatter a base plate 21, carryinga scale 22, is rigidly affixed. The hook23 of the scale supports a yoke 24, upon which latter a roller 25 isjournaled and has a strap 26 engaged there over, the strap having aseries of apertures 27 in its free end. The opposite end of the strap 26is connected to a bracket 28, which latter is provided with hooks 29 and30 en gaged through apertures 33 and 34 of straps 31 and 32respectively. The straps 31 and 32 are engaged over and with rollers 35and 36 journaled in slots 38 and 39 provided for their reception in theend 19 of the box. The opposite ends of the straps 31 and 32 extendwithin the box and are connected to a cuff 37 which latter is secured tothe injured limb, to hold and support the latter.

For the purpose of supporting the box in a horizontal plane, a support40 is provided which support is hinged at 41. to the base board 1, andhas an outwardly projecting finger 43 which engages with the free end ofa leaf spring 42, which latter is secured at one end to the base board1, and has its said free end movably projecting into a cut-out portion42' provided therefor in the upper face of the base board 1, as depictedin Fig. 8 of the drawings. with the box as shown in When engaged Figs. 2and 4, the

support 40 will hold the box against up and down movement, and when suchup and rides over and depresses When in vertical raised the spring 42position the spring 42 acts to hold the support rigidly in position, asis obvious.

Apertures 44 are provided in the sides of the box to enable a strap (notshown) to be placed through to therehold the limb within the box,

and latches 45 and 46 are employed, as

shown in Figs. 1,

2 and 4 of the drawings to hold the sides of the box in verticalposition. For the purpose of restrictingthe combined lateral rotatableand longitudinal movements of the box,

stops 49 and 50 as shown in Fig. 2 are provided for the purpose ofengaging the T-fitting 8.

In operation the sides of the box are unlatched and lowered, and

the injured limb is thereupon placed within the box, and secured to thecuff 37,

after which the sides of the box are returned to vertical position andlatched in such position. The operator then grasps the strap 26 andexerts a downward pull thereon,

the amount of the pull being indicated by the scale 21, the extent ofpull depending upon the requirements of the special case being treated,and being constantly indicated by the scalewhich at all times pointswhich the limb is subjected-to.

to the pounds pressure The straps 26 upon the desired pull upon the legbeing attained, then has one of its apertures 27 placed over the hook48, so as to main tain the desired tension on the leg. Should thepatient desire to move the box back and forth longitudinally, pivotsupon the stud the fitting 6 which shaft 5 allows of such movement, whilethe stud shaft 9 within the sleeve 7 has partial rotary movement thereinenabling the box to be rocked or rotated partially in a vertical also beoscillated plane and the box can longitudinally about the pivot 12, fromwhich it will be apparent that the box which retains the limb ispermitted to have practically a universal movement. I The inventiontherefore is adapted to either enable the leg to be held stationary byuse of support 40, without five cents said support to allow the patientto move the leg within certain bounds without friction or strain, incases where discomfort results from constant maintenance of the leg inone position.

'What is claimed is 1. In a fracture setting apparatus, a base, a studprojecting up therefrom, an L-fitting journaled on the stud and having ahorizontal sleeve, a T-iitting having a stud which projects in thesleeve, a pin and slot connection between the sleeve and the stud whichprojects thereinto to allow partial rotary movement of the last namedstud, a limb receiving box, and a stud extending first named means torestrict the extent of the box to the base horizontal oscillatorymovement of the box.

' 3. In a fracture setting apparatus,

abase, a member havlng a vertlcal part and a horizontal part, means torotatably connect the vertical part to the base, a box, an elementhaving a horizontal part rotatably and slidably connected to thehorizontal part of said member, means to restrict the extent of relativerotary and sliding movements of said horizontal parts, a vertical parton said element, and means to rotatably connect the box to said verticalpart of said element.

4. In a a member having a vertical part and a horizontal part, means torotatably connect the vertical part to the'base, a box, an elementhaving a horizontal part rotatably confracture setting apparatus, abase,

nected to the horizontal part of saidmem ber, means to restrict theextent of relative rotary movement of said horizontal parts, and meansto rotatably connect the box to said horizontal part of said element.

In testimony whereof I affix my signature in presence of two witnesses.I
